In the APU system, the CPU performs the operation in the way of serial code execution, and the software mode is difficult to achieve accurate timing, so it is a better choice to call the internal timer hardware to complete timing. In this paper, timer interrupt control LED periodic flicker as an example to learn the use of private ti ...
